With the arrival of more and more intelligent times of electrical appliance application, the requirements on the functions and the safe operation of the switch are higher and higher, and particularly the application on a photovoltaic power station is realized. But the general photovoltaic power plant area is big, the distance is far away, and isolator itself is used for cutting off fault circuit and guarantees electrical circuit and personal safety, for example when the photovoltaic module breaks out conflagration or trouble, when the circuit reduces the loss needs to be in time closed, utilizes the manual work to go to operate rotatory isolator, hardly makes quick cut off circuit, is difficult to ensure operating personnel's safety moreover.
